He, nice to see that there is always something one didn't know
about Emacs.

With this command you can forget about the narrowing.  It's
doing all you want (well nearly, you still have to mark the

   C-a C-SPC C-e M-x canonically-space-region

>       (line-beginning-position) (line-end-position)))))

Or your code a bit compressed:

(defun just-one-space-in-current-line ()
  (canonically-space-region (point-at-bol) (point-at-eol)))
